Reference voltage source

A reference voltage source comprising:

• a plurality of master resistors connected in series to define a master stick with two ends, the master stick having:
• a first compensation node at the first end of the master stick,
• a last compensation node at the second end of the master stick, and
• one or more intermediate compensation nodes therebetween;
• a plurality of slave resistors connected in series to define a slave stick having:
• a first primary output node corresponding with the first compensation node,
• a last primary output node corresponding with the last compensation node,
• one or more intermediate output nodes therebetween, each corresponding with a different one of the intermediate compensation node, and
• between each adjacent pair of primary output nodes, one or more secondary output nodes;
• a plurality of compensation resistors, one such resistor associated with each compensation node, each such resistor connected between its associated compensation node and the corresponding primary output node;
• means for causing a slave electric current to flow through the slave resistors and generate a reference voltage at each primary output node and each secondary output node;
• and
• means for causing a master electric current to flow through the master resistors and generate at each compensation node a compensation voltage that differs from the reference voltage at the corresponding primary output node by a magnitude sufficient to cause a compensation current to flow through the associated compensation resistor into the corresponding primary output node such that the sum of the currents flowing through all the compensation resistors is approximately equal to the sum of the load currents drawn from all the output nodes.
